' TYPE-WRITING MACHINE.

Specification of Letters Patent. Application filed March 10, 1910. Serial No. 548,465.

Patented Sept. 13, 1910.

To all whom it may concern:

Be it known that I, CURTIS HoLLANo, a citizen of the United States. residing in Butte, .county of Silverbow, State of Montana, have invented a certain new and useful Improvement in TypeWVriting Machines, of which the followingv is a specification.

This invention relates to certain improvements in typewriting machines whereby I combine a former attachable device for indicating the approach of the end of the type writer paper with a new and novel form of construction for the platen end piece. In the present invention I have endeavored to further simplify the device, both in construction and in the manner of application, by adding an annular flange to the ordinary platen end piece, making it, preferably, integral therewith; providing one or more peripheral rabbeted run-ways, and positioning a movable ring-like scale upon and surrounding the periphery of the said flange. The virtues of my former attachable device may well be attributed to the present mechanism, but with the main and special object in view of making it more of an inbuilt feature, for the machine adopting it, than as an extra and attachable device.

The present invention provides a device by the use of which it will be possible to determine, at a glance, just what portion of the typewriter paper remains unwritten u )on, and further provides means for p ainly indicating, at the proper moment, furious marginal end limits.

\Vith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the acconnan in drawin s and )artic- D C) 7 ularly pointed out in the appended claims. Figure 1, shows a plan view of the platen end piece, of my design, detached from the )latcn-roll. Fig. 2, shows a cross-sectional view of the platen end piece attached to the end of the platen-roll. Figs. 3 and 4, show top and side views respectively of the movable ring-like scale 3. Fig. 5, shows an end or side view of Figs. 1 and 2, while Fig. (3, shows a partial development plan of Fig. 3, as it. would appear straightened out. Figs. 7 and 8, show top plan and end views respectively of the complete indicating mechanism attached to the end of the platen-roll, and also shows one method for securing the consists l and 2, has a raised and centrally disposed rib 5, upon its periphery, forming annular rabbeted run-ways (3, which are engaged by the depressed portions 7, and by slitted spring-like registering members 8, integral with the movablering-like member 3, serving to position and retain said member upon the periphery of the flange t.

The slitted and inwardly bent spring-like registering portions 8, serve to grip the rubbeted run-way (i, and cause the indentation 9, to snap into further engagement with the deeper notches or indentations 10, within the rabbeted run-way 6, thus setting and indexing the movable ring-like member 3, in the position desired and normally preventing rotary movement.

The annular raised rib 5, bears characters upon its periphery, and between the rubbctcd run-ways, representing various sizes of typewriter paper, as for instance, 5-}, 11. and 13, the character representing the l3 size being positioned as shown in Fig. l.

The movable and scttablc ring-like scale 3,'l ig. G, has apertures 11, 1'2 and 13, at certain points representing various marginal end limits, as for instance, 2 inch, 1 inch and inch respectively, and also bears a character at 14- indicating the starting position for the roller for the 13 size paper, and also bears a mark at 15 indicating the starting position for both the 5-1- and 11 sizes of paper. To facilitate the loosening and tightening of the set-screw 16, from or against the roller-shatt, is the object of the hole 17 in the flange 4., as shown in Fig. 2, through which a screw-driver may be inserted for the purpose stated.

The movable scale 3, consists of athin metal ring-like band positioned upon and encircling the periphery of the flange l, and I have so proportionedand positioned the apertures in the movable ring-like member, with reference to the characters on the flange that only one set of figures, reprewhere 13,

termined senting the size of the paper being used,

adapted to be engaged by a point and the scale thus revolved and set at the desired position. I

A fixed index member19, on the carriage frame 20, is so constructed that a slight pressure of the finger will cause a depending stud 21, carried at the end of the said index member, to engage with one of the perforations 18, and by turning the roller 2, either forward or backward, as the case may require, the scale 3, may be moved and the desired set of figures on the flange thus brought into view through either the 2 inch, 1 inch or the 3 inch aperture in the scale. Thus, for instance, if it is desired to use 13 inch paper allowing a 2 inch margin at the bottom of the page, the scale 3, is moved until 13 appears in the 2 inch aperture in- .Fig. 7, shows this combination the size of the paper being used, appears through the aperture '11, indicating the 2 inch marginal end limit. The fixed index member 19, is adapted to aline with the starting position for the roller, and also serves as a stopping marginal character comes into alinement. After once setting the scale 3, for thesizc of paper it is desired to use any number of pages may be written thereafter without adjustment of the indicator, the only matter requiring attention being simply the starting position for the roller. By turning the roller the indicator, as a whole, revolves therewith, thus bringing the starting character on the scale 3, into alinement with the fixed index member 19, indicating the position of the roller for the insertion of the paper and the starting oil point. Certain revolutions of the roller 2, will bring 13 into alinement with the index member 19, thus showing that that line may be written upon and still leave a 2 inch margin at the bottom of the page for signature, or in the case of billing, for the computation. From this it will be seen that if either 11 or 5; through the 11 aperture, a 2 inch margin would be the result for either of these sizes when they are brought into alinement with the index member 19, and if either figure was set to appear in the 12 aperture a 1 inch margin would result; Moving the scale 3, either forward or baclnvard produces a like change in the position of the starting characlm's, with regard to the figthe scale ures on the flange.- lt will be seen that it is necessary lo make this change in the starting position for, the roller, for the different sizes of typewriter paper, wlth regard to the stopping posit on, 1!] order to obtain the different {marginal end limits. For the point when the predeare set to appear sake of illustration, 20, represents a portion of a Remington frame, but the manner of attaching the fixed index member 19, theretodoes not limit the device to this manner of attachment alone, as other means may be employed, and other forms of index members the purpose for the various makes of machines. Certain carriage frames are so constructed that the fixed member 19, may be dispensed with, a portion of the carriage frame or platen spring clips with a mark, serving the same purpose for alinement and in that case a. pencil point, for instance, may be used for engaging the perforations 18, for moving and setting the scale 3.
